MICH'GAN, .A CORPORATON OF Application filed January 7, 1924S7era1 No.6`l4,753.` Renewedveptelnber 27, 1926.

rllhis invention relates to barriers between Ahigh tension conductorsand apparatus in electric power plants and the like, and has 'for itsprimary object the provlsionot a barrier termed otdeinountable sectionsof 1n- .sulatino' materials that ma be readil. as-

sembled or dismantled .at will. n

Another object ot` my invention isthe construction or" barrier sectionslot "tire proof as D well as electric insulating materials` arrangedmassive barriers that limit the disposition ot conductors and apparatustothe plan preconceived betore the building was erected. A rearrangementto accommodate new apparatus or more eilicientlyutilize the buildingcannot beaccomplished without demolishing large portions of the wallsand flooring.

My invention overcomes these ditliculties, providing a barrier combiningelectrical efficiency with lightness of weight and which can be quicklyand inexpensively installed and removed whenever desired 4withoutdoeingdemolished.

Gtherob'ects and advantages will be apparent from the followingdescription, wherein reference is made to the accompanving drawingsillustrating preferred embodiments of my invention and wherein similarreference numerals designate similar parts throughout the several views.

ln the drawings:

Fig. 1 is a detail sectional view through one side wall, floor andceiling of a room in a power house.

Fig. 2 is an elevation of the disclosure in Fig. 1, looking 'from theright of Fig. 1.

3 is a detail elevation showing the manner ot suspending barriersections from a ceiling or the like.

Figs. 4 and 5 are detail sectional views taken respectively on the lines1 -l and 5-5 in Fig. 3.

Fig. 6 is a detail elevation, showing the manner of suspending barriersections adjacent aside wall, to which they may bealso supported.

Figs. 7 and 8 are detail sectional views taken respectively on lthelines 7 7 and 8--8 in Fig. 6. Referringnow to the drawings, the numeral5 designates the ffloor ofan electric power plant',T and the numerals '6and'7 .the sidewall and ceiling. of ajroomtherein. An electric v powerplant is shown f by waynffez'- ample because there are'vlocatedelectrical apparatus and conductorsadapted jto'Ca'lry hightension loadsandl accordingly the need of barriers involving theprinciplesfothis invention are particularly useful'. 'Itis tobeunderstood, however, that fmy'ibarriers are valso useful in otherlocations-4in fact, wherever high tensionconductors or ,apparatus areinstalled.

.ln Figs. 1 and 21a pluralityotl .electric apparatus S and bus bars 9areseparated'by barriers 10 soas to isolate the several electricmembers, and also to :insulate .thfem against possible arcing. Eachbarrier is formed ot `a plurality `of demount-able .sections 11 formedoflire proofl as well aselectric 'insulating materials, such as tile,terra cotta, concrete, gypsunnor the like, andarranged to be .detachablysecuredto ,a horizontal Vor verticalportion ofthe power plant,

suchfas the ceiling 7 or side wall 6. The sections may also be formedwith interlocking portions to insure accurate alignment 'wan-d also .toaid in 4preventing v,accidental openings between sections. As bestillustrated in Figs. 5 and 7, the opposite side edges of the sections 11are formed with interiitting tongues and grooves 12 and 13 respectively.Each section is preferably Jformed with parallel ribs 14 of greaterthickness than the remaining portions of the section, so as to give apanel effect and also to provide portions of suiiicient thickness topermit the provision or' apertures throughout the section for thereception of detachable bolts or other securing elements ofnon-insulating material. As best shown in Figs. 3 8, certain of the ribsare apertured to permit the passage of elongated bolts 15, one extremityof which is embedded or otherwise suitably secured in the ceiling orother walls of the power plant, andare threaded at their oppositeextremities to receive nuts 16 or other detachable means for locking thesections on the bolts.

In Fig. 3 a single section is shown suspended from the ceiling 7 bymeans of a bolt 15, while in Fig. 6 is shown the abutting horizontaledges of upper and lower aligned sections adapted to be suspended fromthe ceiling on the same elongated bolt a. It will be apparent that, byaligning the apertures in the ribbed portions of the sections, as manysections as desired can be suspended from a ceiling or other horizontalsupport. If desired the barrier sections can also be supported from thevertical side wall 6 by means of tie rods 17 extending from the wall toa lug 1S on the free edge of the lower most section 11 of the barrier, anut 19 or the like being threaded upon the free extremity of the tierod. It will also be apparent that by extending the bolts 15 in ahorizontal direction from a side wall or other vertical support,individual sections can be supported directly against the side Wall.

From the above it is believed to be apparent that I have providedbarriers of fire proot as well as electric insulating materials that arecapable of ready installation at any desired location, the alignment ofadjacent barriers being automatic and the mounting of the barriersections being easily understood by an ordinary mechanic or builder. Thebarrier will retain its position as long as desired, and can then bequickly dismantled without demolishing` the barrier sections or theadjacent walls. Moreover, a single section or a group of sections can beremoved at will.

The provision of the securing apertures within thickened ribs permitsthe insulation of the bolts or other securing elements without weakeningthe barrier, and the provision of thinner panels between adjacent ribspermits the ready breaking away of one panel should it be desirable topermit the passage of cross members through barriers already erected.

While it will be apparent that the illustrated embodiments of myinvention herein ,disclosed are well calculated to adequately 2. vAbarrier between conductors and apl pa-ratus in electric power plantscomprising a plurality of interlocking sections of fire `proof andelectric insulating materials, the

sections being provided with apertures extending from edge to edge toreceive securing elements.

3. A barrier between conductors and apparatus in electric power plantscomprising a plurality of interlocking sections of ,'[ire proof andelectric insulating materials, the sections being formed with aperturesparallel to their faces, and securing elements adapted to be fixed to awall of the power plant and to extend through said apertures.7 i

4. A barrier between conductors and apparatus in electric power plantscomprising a plurality of sections formed of fire prooil and electricinsulating materials, each section being formed with parallel ribs ofgreater width than the remainder of the section, and certain of saidribs being provided with apertures parallel with their faces to receivesecuring elements, and securing elements adapted to extend through saidapertures and be fixed upon a wall oft the power plant.

In witness whereof I hereunto set my hand.
